The methods of synthesis of the pyridinium salts (IIIa-e) and bis-pyridiniumdiperchlorate (IV) were described in our study [5]. lp-Aminophenyl-2, 6-diarylpyridinium perchlorates (IIIf, g) were produced for the first time by the reaction of pyrilium salts (Ib, c) with p- phenylenediamine in boiling glacial AcOH medium, r
